Be it known that I, DEAN'EJLoo eN, a

citizen of the United Stat residing at Salem, in the county ofEs'sex and State of Massachusetts, haveinvented new and useful Improvements in Safety-Razors, of which the following is'a specification.

This invention relates to improvements in razors and particularly to that type lrnown as the safety razor. r 1

. The obj ectlof the invention isto providea safety razor comprising a blade having notches atopposite ends thereof'anda single 'means adapted to project into saidnotches' to perform a threefold purpose, namely, to position said blade longitudinally and laterally thereof and to yieldingly hold said blade transverselythereof, thereby producing a razor which will be inexpensive to same.

.Referring to the drawings: Figure 1' is a perspective view of arazor. einbodying my invention. Fig. 2 is a sideelevation of the Fig. 3 is a detail plan view of the razor bladeused in connection withfmy invention. Fig. 1 is an enlargedsectional elevation taken'on line 3, 3 ofFig; 2 as viewed in the direction of the arrows on said line. Fig. 5 is a perspective view of a'inodified form of spring for secur in the razor blade on the holder, a portion o therazorblade being shown in said figure Fig. 6 is end view of the blade illustrated in Fig. 3.

Like numerals refer to like partsthroughout the several views of the drawings.

' In the drawings, 8 is a holder, of" a well known type, which comprises a blade support 9 haying guard'10 provided with the usual serrations 1 1. The holder 8 is further provided with a depending'portion 12 which is connected at its upperend to the rear edge of the blade support 9 and at-its lower end With a handle'13, f v r A razor blade 14, which is rectangular in shapeand formed from a piece of thin sheet material, is provided with a single cutting edge 15, While said blade is preferablyreinforced at its rear edge by a'U-sh'aped member 16 extending substantially the length of sald rear edge, and adjacent to'the ends of said reinforcing member 16 are notches 17,

17 for xthepurpose hereinafter set forth. The razor blade 14 is arranged to rest upon the holder 8 against the upper surface of the blade support 9 with the cutting edge ,15 parallel with the front edge of the guard 10 and above the serrations 11. To facilitate the positioning of said cutting edge relatively to said guard 10 and serrations 11, stops 18 are provided which are preferably formed by partially detaching a portion of the material constituting the holder 8 .at points adjacent to the opposite ends of said guard, stops l8 permitting the cutting edge of said razor bladeflto project thereenea \thHSllOt .Only preventing a move- The invention consists in the combination ment of the cutting edge toward the edge of said guard 10, but also preventing the ;move nent of said jcutting edge laterallyof said razor b ade uppor y om e s mtions 11, said stops being long enough .to per- Init ofa slight movement of'the cutting edge toward and away. from the frontedge of the guard 10 without said edge becoming disengaged therefroin. The rear edge of the blade 14 is engaged by means adaptedto position said blade longitudinally thereof and laterally relatively to the blade support 9, and'furtherrnore said means is adapted to yieldingly press'said blade toward the front of'the guard 10 until its cutting edge en-' 9 and position said blade longitudinally thereof'on said holder. By providing the notches 17 it will be obvious that onemember, such for instance, as the arm 21 of the forked spring 19, will be capable of engaging both edges constituting said notch and thus position said blade both longitudinally and transversely thereof, it being much cheaper and far preferable to form said notches insaid blade than to construct the arm on said spring in such a manner that it will be able to engage both the rear and end. edges of said blade, because with the notches in the blade less space will be utilized and said spring will be least exposed and less liable to interferewith the use of said razor.

To retain the rear portion of the blade 14 in p contact with the upper face of the blade support 9, lugs 27 are provided adjacent to the free ends or extremities of said arms 21 to engage the upper face of said blade 14. These lugs are .preferablyformed in the same manner as are the stops18, that is, by

partially detaching a portion of the materialconstituting said forked member 19 and forcin said material laterally of the front face 0% said forked spring. In placing the blade 14 upon the holderS the-cutting edge 15, as hereinbefore stated, is placed beneath and against the'stops l8. Toinsure the proper positioning of said blade longitudinally relatively to said holder the extremities of the arms 21 are provided with beveled inner faces 28 and these faces are engaged by the edges 26 during the downward movement of the rear edge of said blade and consequently move said blade lengthwise in one direction or the other as the case may be until said blade strikes the upper face of the blade support 9 at which time the edges 26 will engage the inner edges 25 of the arms 21.

' back by the reaction of the arms 21 until the front faces of said arms engage said edges 24, thus said blade will be securely locked in this position on said holder 8.

When it is desired to remove the blade 14 from the holder 8 to strop the same or to replace it with another blade, the rear edge of said blade is released by deflecting the forked spring 19, thus detaching or disconnecting the lugs'27 from the upper face of said blade. To facilitate this and the Simultaneous movement'of both of the lugs 27 a finger piece 29 is provided upon said spring 19, the same being preferably formed integral with said spring and extending from the rear thereof through an opening 30 in the portion 12'of said holder 8 and in" a posit-ionto be engaged by the'finger andv to be manipulated thereby to disengage the lugs 27 from the upper face of said blade 14, as hereinbefore stated. ;Upon the movethen be invert-ed and the blade will be free ment of said member 19 the holder which is being held by means of the handlef13 may;

to drop therefrom disengaging-itselffrom the stops 18.

In Fig. 5, I haveshown'another form of} spring for retaining the blade in place upon the blade supporting member 9. In'this figure the spring 19 is, in constructionsirnilar to the spring 19, illustrated in Fig.4, the

only diflerence" being that the extremities of the arms 21 are bent laterally thereof at 31 and theselateral portions are turned up,

wardly at their forwardends to provide a rounded face 32. This construction pro,- Y vides a more substantial securing meansthan would be possible with that illustrated in Figs. 1,2 and 4, the blade beingconstructed in the same manner as hereinbefore stated. WVith this form of spring the blade may be put in place upon the holder" 8 in the same manner in which the blad eis positioned in the form hereinbefore' described,

that is, by, manipulating the fingerpiece 29" to deflect the arms 21 or if desired,:,the 7 blade may be grasped between the thumb and forefinger and the back of said blade placed against the arms 21 with the edges 24 of said'blade engaging the front faces of said arms 21--b eneath said lateralpro- I jections 31 and pressing said blade backi wardly sufficiently to permit the cutting edge 15 to be placed" beneath the stops 18 and upon releasing said bladethe reaction of the spring 19 will cause said-blade to slide beneath said stops 18 and in this form, r V

as in the other form, said blade will be yieldingly retained in its proper relation to the guard 10, thus increasing the efliciency of the razor, as it hasbeen found that a yielding cutting edge is superior toa rigidly supported cuttingedge. Having thus described my invention, what I 'claim and desire by Letters Patent to secure is: V

A razor having, in combination, a razor blade provided with notches at the rearvcorf ners thereof, a holder, means for positioning the cutting edge of said blade relatively to said holder, a forked member secured to said holder, the members thereof constituting said forkadapted to project into said notches to yieldingly press said bladeagainst said positioning means the extremities of the members of. said ork havingbeveled faces adapted to engage the ends of said In testimony whereof I have hereunto set blade Within said notches, to position said my hand in presence of two subscribing Witblade longitudinally. of said holder, and lugs nesses.
